Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new ...

Graphene Flagship scientists based at the University of Groningen, The Netherlands, have created a device based on a blilayer of graphene and boron nitride which shows unprecedented spin transport efficiency at room temperature. ...

Researchers report that it is possible to move a nanoparticle on the surface of a graphene sheet by applying a temperature difference at the ends of the membrane—a nanocluster on the surface will drift from the hot region ...

A new featherweight, flame-resistant and super-elastic "metamaterial" has been shown to combine high strength with electrical conductivity and thermal insulation, suggesting potential applications from buildings to aerospace.

The strongest material known to mankind was first discovered with sticky tape. Today, this two-dimensional (2-D) version of carbon known as graphene is the subject of intense research around the world. Many hope its unique ...

Researchers have designed a graphene-based tattoo that can be directly laminated onto the skin with water, similar to a temporary tattoo. But instead of featuring artistic or colorful designs, the new tattoo is nearly transparent. ...

Rice University chemists have produced a catalyst based on laser-induced graphene that splits water into hydrogen on one side and oxygen on the other side. They said the inexpensive material may be a practical component in ...

Graphene

Graphene is a one-atom-thick planar sheet of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice. It can be viewed as an atomic-scale chicken wire made of carbon atoms and their bonds. The name comes from GRAPHITE + -ENE; graphite itself consists of many graphene sheets stacked together.

The carbon-carbon bond length in graphene is approximately 0.142 nm. Graphene is the basic structural element of some carbon allotropes including graphite, carbon nanotubes and fullerenes. It can also be considered as an infinitely large aromatic molecule, the limiting case of the family of flat polycyclic aromatic hydrocarbons called graphenes.

Measurements have shown that graphene has a breaking strength 200 times greater than steel, making it the strongest material ever tested.
